One may do something during one's whole life and accomplish it to a great extent, but through lack of a little more faith one will lose it, and all that was done will be spoiled in a moment's time. How long does it take for a house to be built, and how long does it take to destroy it? How long does it take to make a business really prosperous? How long does it take to fail? One moment. When one learns this principle and thinks about it, one begins to see that the whole world, with all that we hear and see and touch and feel, is all illusion in the face of faith. Faith alone is reality, and compared with faith all else is unreal. But since we do not see faith with our own eyes, it is very difficult to call faith real and all else unreal; our eyes cannot see faith and we do not know where it is.
